Generally, the particle size of concrete is graded, between 5-25mm. Graded gravel Graded crushed stone is a mixture composed of fine aggregate, coarse aggregate and stone chips in a certain proportion. When the particle composition meets the requirements of dense grading, it becomes graded crushed stone, which is generally used for less traffic.

Clast Size & Sorting When studying sedimentary rocks, the one of the most obvious aspects will be the particle or clast size. Determining whether a sedimentary rock is composed of sand-sized, silt or clay, or gravel is the first step in identifying clastic sedimentary rocks. The following table defines these terms based on average particle diameter.

2017528· Soil-Particle Size The sizes of particles that make up soil vary over a wide range. Soils are generally called gravel, sand, silt, or clay, depending on the predominant size of particles within the soil. To describe soils by their particle size, several organizations have developed particle-size classifications.

Both terrestrial and marine sediments are classified by size using the same scale. Boulder is the largest particle size, followed by cobble, pebble, gravel (or granule), sand, silt and clay. It takes energy to move particles. The larger or heavier the particle, the more energy it will take to move it.

329· Sand is a naturally occurring, finely divided rock, comprising particles or granules ranging in size from 0.0625 (or 1⁄16) to 2 millimeters. An individual particle in this range size is termed a sand grain. The next smaller size class in geology is silt: particles below 0.0625 mm down to 0.004 mm in size.
